I was reviewing the page-grammar-001 test, and noticed that there's no normative
grammar for the @page rule. The test refers to Appendix G, and asserts that
white space between @page and a selector is optional; however this is nowhere
stated in the spec.
Proposed to add after
# An @page rule consists of the keyword "@page", followed by an optional
# page selector, followed by a block containing declarations and at-rules.
the following:
| Comments and white space are allowed, but optional, between the @page
| token and the page selector and between the page selector and the block.
